Specification of Letters Patent. Patented .F b 14 1922.

Application filed. March 10, 1321. Serial No. 451,411.

Dominion of Canada, have invented certain new and useful Improvements 1nMultiple a device of the character indicated involving unit mold formingmembers, each including a base plate adapted to be supported on onelongitudinal edge and having applied thereto a series of right angledplates disposed in contiguous alignment on said base plate, with one legoverlying the base plate and the other leg normal thereto, and endplates to whichthe several parallelmold forming members are secured, sothat the seriesof 1 legs of the right angle plates on the front face ofeach base 'p late engages the rear wall of the adjacent parallel baseplate.

whereby the majority of the individual mold units are formed by the twotypes of elements, represented by the base plate and the attached rightangle plates, and the multiple mold as a whole is made up of theselatter members and the end plates. and may be quickly assembled andknocked down, and

'may also be extended indefinitely in a longitudinal directionby'juxtaposing and corn necting assembled multiple'units made up of theparts as indicated.

The foregoing and other novel features of the invention will be moreparticularly set forth in the annexed specification, predicated upon theaccompanying drawings, in which r p Fig. 1 is a perspective view, brokentransversely through the mid section, showing the multiple mold carriedby a truck; I

Fig. 2 is a broken perspective view of one of the supports which maybeused in connection with the mold; r

Fig. 3 is a broken perspective view of one of the end plates; and I Fig.e is a perspective view of one of the unit mold forming membersassociated with one of the base supports.

Referring to the drawings, 1 indicates the base plate of one of themultiple mold forming units, which plate 1 is preferably provided withend lugs 2 which may be formed integrally therewith or secured thereto.Flrmly secured by any suitable means, such as riveting, welding or thelike, to the face of the base plate 1 is a series of mold formingplates, including a leg 3 overlying the base plate and a leg l normalthereto and to the base plate. These right angle mold members,comprising legs 3 and 4, are arranged in longitudinal abutting series,and

the last member of the series is preferably formed by the slngle plate'3 with no right angularly disposed leg, as thefunction of the latterwill be subserved by the endplate which crosses the open ends of all theindividual mold sections, as will be more particularly'explainedhereinafter. The inner face of each of themold members 3 and 3' isprovided with a projection 5, which may take any desired form, and whichconstitutes the core for formingthe frog in the block or brick. 7 l

In order to build up a multiple mold, the series of the units, such asillustrated in Fig. 4, are assembled in parallel relation with theangular legs 4 normal to each base plate engaging the rear face of theadjacent base plate, as illustrated'in Fig. 1, and, when the units havebeen assembled in requisite 1 number, end plates 6 are applied, by pass-;ing the tongues 52 on the respective ends of unit base plates 1 throughslots 8 in the said end plates. The end plates are also provided withyertical angle bars 7, which determine the widthof the multiple moldsection, the

base plate of the initial unit being supportmay, if desired, be, a plainsection of the same dimensions as the other base plates,

which'is engaged behind the angle irons 7.

In other words, the final base plate 1 may have the mold formingsections, formed by a the rightangle plates 3 and L, omitted therefrom,but in other respects is substantially identical with the other baseplates 1,

hen a multiple mold is to be assembled on a smooth floor or molding bed,the base plates 1 and the right angle plates attached.

which will present a smooth surface forthe. bottom of the multiplemolds, and the sup? porting element is preferably made in the form shownin Fig. 2, involving a relatively wide face plate 15, which is ofsubstantially the same length asbase plate 1 of the indi-v vidual moldunits, and'which is supported by angle irons 16, the whole constitutinga bench like element, and when several of these are arranged sidebyside, they will constitute a smooth, level support for the entireseries of mold sections. When the apparatus is used: in conjunction withthe supporting elements, certain of the base plates 1 are made 01 a:greater depth than the attached mold plates 3 and 4:, ed that the lower,edges of the deeper base plates shall overhang the edges of thesupporting-plates 15, thereby not only insuring the proper adjustmentand alignment-of the variousbase plates, but materially strengtheningthe as sembled mold asa whole. The supporting elements 15 may, ifdesired, be made wide enough to receive several ofthemold formingsections carried. by the individual base plates, 1, in which event" onlythose base plateswhich lie adjacent the lateral edges of the supporting,members 15 would be extended downwardly, to a greater depth than themold forming plates carried thereby. Such a disposition and=arrangementof the supporting member 15 is illustratedl-in' Fig. 1, in which themultipleymold is supported on a truck, the'latter having theusualframework, including transversebeams 20 and supporting wheels 21, said,crossbeamsbeing provided, with cleats or abutments 23 properly spaced toreceive the endpla-tes 6 as well asintermediate spacings blocks 24interposed between theucleats and the base plates or mold sections to.prevent-the latter being sprung" out of shape. Any suitable means may beprovidedforpositively looking the individual base plates or mold formingunits to the end plates, sothat theassembled multiple mold may retainits, proper shape, and, when such an assembled multiple mold orlongitudinalseries of multiple mold frames are applied to a supportingtruck, as illustrated in Fig. 1; the-latter is provided with upwardlyextending yoke or stake members 22, betweenwhich and, the endplates 60fthe mold section or sections wedgesoi other clamping. means may beapplied.

As, indicated, the multiple moldmay be extended longitudinally byplacing-two or more of the frames, with the assembledgmold formingelements therein, in longitudinal alignment, the. end plate6ofroneofithe mold frames serving; as adivision plate, be. tween the twosections, the slots 8 therein preferably being made large enoughtoreceive-the1lugs-on the-ends ofthebase plates of; each section,

From the foregoing description it will be apparent that the apparatusinvolves material elements oi": economy in construction and application,in that, in its simplicity of form for use on smooth and level floors,it includes only two types of individuale1ements, namely, the moldforming members, each comprising a base plate 1 and mold forming members3 and 4 attached thereto and the end plates -6, and evenwhenitheapparatus is employed Wltllitllfi separate supporting members 15, thenumber: of unit types are increased by two only, the sup-' portingmembers 15 and the mold forming members,includingthe deeper baseplates 1. The apparatus is also much simpler and more efiicient inoperation than similarxdevices, as heretofore developed, in that'itmaybe readily assembled by unskilled laborers,

and, after the pour haspbeen made, and the bricks or blocks allowed toset; the entire apparatus can be quickly takendownlto release the bricksor-blocks WithOUt danger. of damaging or chippingtheflatter',assthelmold forming sections maybe readilywitlrdrawnlaterally from theirows of'molded bricks or blocks as soon as the endplateshave; been displaced. Furthermore, the simplicity of theconstruction insures the apparatus and the elements thereof againstdamage or impairment duringordmaryusage, and, should any one ofthe unitsbedamaged', it may be readily replaced by another, as all of the unitsof the same type -are-interchangeable What I claim is: 1 1 a '1.
